摘要
DMD-B型堆码机采用sI MATIC s7-1 200 PLC作为控制平台,扩展方便,通讯能力非常强大。上位机采用RS485 MODBUS协议与PLC通讯连接,人机界面与PLC采用以太网进行通讯。整套系统能完成人机界面交互操作、I/O逻辑运算、故障诊断及通讯等功能。
As the control platform of DMD-B Stacker, the expansion of S7-1200 PLC is convenient,and communication ability is also formidable.The upper computer use RS485 MODBUS communication protocol connection with the PLC,and the HMI use Ethernet communications. The entire system can finish human-machine interaction interface, I / O logic operation, fault diagnosis and communications functions.
